Rush admits he's a fan of Curtis Jones and fellow Welshman Neco Williams.
He told 888Sport: "When I played for Liverpool, every summer we would sign two players. One experienced player and one younger player. Now Liverpool's academy is that good they can forget about the younger player because they are bringing them through.
He added: “He is up there simply because this is the first time Liverpool have won the league in thirty years. Bill Shankly put the foundations in and Bob Paisley took them to a different level, and then you have Kenny Dalglish who was the last manager to win the league. Let's not forget too that great managers have tried to win the league with Liverpool and failed.
"So Jurgen is a hero right now and if Liverpool retain the title then for me, he is right up there alongside Shankly and Paisley and Dalglish."
